FIBBOUS CAP FOR BOTTLES AND OTHER CONTAINERS.

Specification of Letters Patent. Patented Dec, 19, 1916 Application filed February 4, 1914. Serial No. 816,518.

To all whom it may concern:

Be it known that I, ALBERT WESTLAKE, a

. citizen of the United States, and resident of the city, county, and State of New York, have invented certain new and useful Improvements in Fibrous Caps for Bottles and other Containers, of which the following is a specification.

The object of my invention is to provide an air-tight, tenacious, non-absorbent, fibrous cap for bottles and other containers, the

mouth of which does not afl'ordthose points of protuberance or recess required by the ordinary external closures, and the delicacy or thinness of which does not permit the employment of much force to'bring about an adhesive contact with the interior of the mouth.

It is a further object of my invention to have this fibrous cap of such shape and character that the bottle or other container may be filled absolutely to the overflow point,

whether the contents are wet or dry, so that.

not onlyis'there no part of the interior space lost, but no air remains in the bottle except such as is contained in the liquid or dry contents thereof.

In the accompanying drawings: Figure 1 is a side elevation of a half-pint milk'bottle provided with my improved fibrous cap. Fig. 2 is the same, the upper part shown in vertical section. I

Same letters indicate similar parts in the diflerent drawings.

A is a bottle, jar or other container made of glass, porcelain or other desired'material.

B is a fibrous cap made of a disk of suit-- able material and so placed upon the bottle that the central portion thereof, a, lies flat and smooth across the mouth of the bottle and makes an.intimate contact with the top edge 6, of the bottle neck. As before stated it is designed that the interior of this bottle, jar, or other receptacle should be filled absolutely so as to make contact with the lower surface of the middle a, of the cap, and if the contents are liquid so that the upper edge of the mouth is wet at the time of applying the cap, that fact only tends to increase the suctional grip ofthe cap upon the bottle, inasmuch as the diminishing film of air that separates the bottom of the disk from the top of the bottle as they are pressed together during the capping operation is even more readily expelled to form the desired suctional grip when the surface is wet than when it is dry.

Itwill be understood that in applying this cap, a disk of fibrous material previously treated and prepared so as to impart to it the desired and necessary qualities of toughness, pliancy, imperviousness to air or moisture of any kind, and adaptability to proper molding when heated is to be laid fiat and properly centered upon the top of the bottle so as to leave a projecting edge of suflicient length to form the downwardly turned fringe 0. The size of this disk will obviously depend upon the diameter of the bottle top and the distance to which it is desired that the lower edge of the fringe should come down around the neck. When so laid upon the top of the bottle, jar or other receptacle, the disk should be of a temperature sufliciently high to bring out its moldable characteristics as it isintended that after being molded upon the bottle neck, the cap should cool to ordinary atmospherict'emperature and assume a comparatively hard, tenacious and clinging chara'c ter. 4

In forming the fringe c, it is to be observed thatthe fringe to its entire depth becomes folded or plaited in somewhat fine vertical creases or fins f, which are quite un- My improved fibrous cap is designed to be pressed into intimate contact with the exterior surface of the bottle both as-to the inner surface of the finsand as to the inner surface of the fiat portions of the fringe which alternate with the fins so that the in- .terior surface of the fringe obtains throughmotion which proceeds outwardly and downwardly from the point i, to the point It, thus expelling the film of air in the nature of a squeegee.

It Will be found that my improved cap thus applied will afford, as long as it is undisturbed, a complete hermetical seal for the and that when so removed, it Will retain its shape sufficiently to be used as a cover, no longer however hermetical, until the contents of the bottle, jar or other receptacle are exhausted.

I claim: A fibrous cap for bottles and other receptacles which is composed of a disk of suit able fiber having a smooth center adapted to 20 fit snugly upon the upper rim of said bottle, and having its edges turned downwardly and ironed into the form of a fringe composed of alternately projecting fins and flat portions the inner surface of the entire fringe making a continuous air-tight contact with the exterior of the bottle neck.

ALBERT WESTLAKE.
